With Adobe Flash Player installed on your computer, you can attach multiple files to an e-mail. A progress bar next to each file identifies when the uploading is finished. Without the player, however, you may receive an error message and be unable to attach any files.
To correct this, you can install Adobe Flash Player or change the attachments setting in your e-mail.
1. Login to TUmail and click the Gear icon in the upper right corner and then select Labs.
2. Verify that the "General" tab displays.
3. Scroll down to "Attachments," select Basic attachment features... > Save Changes.
